Cut or peel off the skin of the squash, then cut it into large cubes.
Pulse in a food processor in batches for 10-15 seconds, or until rice size.
Keeping the shallot separate, dice the shallot and chives and press/crush the garlic. Combine the chives, garlic and the dried herbs in a ramekin.
Heat oil in a large saute pan on medium-high and add the mushrooms and shallots.
Cook for 10 minutes, stirring occasionally.
Add herbs, garlic and chives and saute for 30 seconds.
Add apple cider vinegar and cook for 1 minute.
Add squash and broth then raise the heat to bring to a boil.
Once boiling, turn down the heat to simmer.
Cook for 12-15 minutes, uncovered, until the squash has mostly absorbed the liquid and is easily pierced with a fork. The squash will continue to absorb the liquid after being removed from the heat.
